Homopolar Motor and Generator Combination

[broli]

Hi Neo-X. I don't think you can hard link to the pictures on the server you sent us a link to. Simply saying - we don't see a picture ;]

EDIT: Sorry, you can right click on the link and choose "Save target as..." - that way it does work.

@Airstriker: Or drag and drop the link in the address bar.

@Neo-X: Here's my feedback. There's one major issue and one wrong statement in your design. The major issue is that you have the wrong magnet polarity. To do what you want to do the magnets have to be repelling. And the wrong statement is that the generator part has no back torque part. The back torque part will be your "external circuit" that is everything that is conducting besides your generator disc. Besides that all I can say is build it and see for yourself. I encourage experimenting more than anything. There's no such things as textbook facts, only what you perceive and experience as fact. Noone in this forum has ever built a homopolar motor feeding a homopolar generator, yet it's a simple feat for some.

Everyone is always lacking money, don't let money guide you but your will power. To achieve something you need to struggle. I recommend you go out to flea markets or junk yards and buy dirt cheap stuff and start building it. You can find anything you want if you know what you want. And start doing this now, because the longer you wait for someone else to "help" the more you realize there's noone coming for help. It's a disgrace but that's our current reality which we should change in our future.

No, I stick to my design and Ill prove that it will work.. Theres no wrong in the polarity. Even if I wrong that the motor disc turn in a opposite direction, a gear can easily fix it...

Don't be so defensive, I didn't say your idea wouldn't work I never say that to anyone. I just brought up some points from experience. If you think I have bad intentions you can wipe your ass with my comments, I wouldn't care less. There's a limit to ignoring pointers though, we can never agree if we argue on something as basic as black and white. You just reminded me of myself so I wanted you to avoid the mistakes I made.

[Neo-X]

I understand you and Im not angry. Sorry if I bother you and thanks for your advice. I hardly of speaking english so I cant communicate normaly..

Actually, you seem like you have the ideas down OK.

You need to do the diagram better to show the brushes
and what is electrically conductive and what isn't.

Like Broli says you probably are going to want to build
it yourself to learn what you are doing wrong.

You are worrying too much about eddy currents in the motor
because the disks should have slots in them. As shown in this
link;

The main shaft can't be one solid piece, if the generator and motor
are going to spin at different RPM's. There will need to be a bearing
and brush inside the the inner diameter of the motor disk.

The mechanical torque times RPM is going to have to be matched to
the electrical characteristics of voltage times current in the motor and
generator. Because the electrical energy (power) can only be changed
slightly. The mechanical power based in the gearing ratio is going to
have to be adjusted to the most efficient RPM operating point after
construction. You currently show it set to about 1 to 81 and I don't
think that is justifiable but I think the numerical ratio is critical.

(Electrical power == Mechanical Power) (+ any overunity power)

In a homopolar device a gearset can be substituted for brushes so
it may make sense to let the negative current flow though the gear
set if the homopolar motor can be fed from the edge?

To get overunity you need to count on a) less backforce in the
generator and b) magnetic field strength increases based in flowing
current. In both the motor and generator case I think it makes sense
to have the magnet disks spin with the rotors.

Good luck...Be sure to watch Bruce's Homopolar Experiment thread.
